[EP-tech] Re: Relevance ranking for Simple and Advanced Search



I'm also using 3.3.12, and confirm the following:

1) Relevance sort was not the default sort option on simple search, but it did show up as an option in the dropdown.  Users had to manually switch to relevance sort.  So my setting for eprints_search_simple.pl doesn't have this:
"byrelevance"    => "",
But I did need to add the following: 
default_order => "byrelevance",
2) Relevance sort was not even listed as an option on advanced search, until I changed the setting to Brian's suggestion.  Now it appears, and the default is set to relevance.

Adam,

Agreed, If Xapian is working then you should at least get an option to order by relevance, but I was not and it also was not set as the default sort either for simple or advanced search.  If there is something in the code that was supposed to do this then it is not doing it at least in the version I'm using 3.3.12.  This is what caused me to come up with the config changes that I posted.  Obviously Tomasz had a similar issue.

So what I would assume (in a perfect scenario) should happen is that if the Xapian search engine is found to be installed, it should:
   a.) Add an order by relevance to both the simple and advanced search.
   b.) Set the order by relevance as default for both the simple and advanced search as this is what users expect to find.

-Brian.

I'm not sure this will work.  In any case, if Xapian is working, you should get an option to order by relevance.  If Xapian isn't working, it can't possibly do you any good.
